Using trellis.par.set seems more successful than specifying par.settings in the call, however much I'd prefer to avoid relying on globals. Example:

ss<-trellis.par.get("superpose.symbol")
ss$pch=rep(19,7)
ss$col=rainbow(7)
trellis.par.set(superpose.symbol=ss)

#Example from xyplot
dotplot(variety ~ yield | site, data = barley, groups = year,
         key = simpleKey(levels(barley$year), space = "right"),
         xlab = "Barley Yield (bushels/acre) ",
         aspect=0.5, layout = c(1,6), ylab=NULL)
